Vishay offers automotive-grade IHLE inductors with integrated E-field shield

Vishay Intertechnology is expanding its IHLE series of low profile, high-current inductors that feature integrated E-field shields for the reduction of EMI with new commercial and automotive-grade devices. These are for the 5 x 5 x 3.4 mm 2020 case size.

The smallest such devices on the market, the Vishay Dale IHLE-2020CD-51 and IHLE-2020CD-5A lower costs and save board space by eliminating the need for separate board-level Faraday shielding.

The devices contain the electric and B-field associated with EMI in a tin-plated copper integrated shield, providing up to -20 dB of electric field reduction at 1 cm (above the center of the inductor) when the integrated shield is connected to ground.

Featuring a high-temperature operation to +155° C and coplanarity of their four terminals within ≤ 100 µm, the inductors are optimized for energy storage in DC/DC converters up to 3 MHz and provide excellent attenuation of noise in high-current filtering applications up to the SRF of the inductor.

Applications for the IHLE-2020CD-51 will include servers and desktop PCs, notebooks, high-current POL converters and power supplies, FPGAs, and battery-powered devices. The AEC-Q200-qualified IHLE-2020CD-5A will be used in automotive engine and transmission control units entertainment and navigation systems, LED drivers, instrumentation panels, ADAS devices and sensors, and noise suppression for PWM-controlled motors.

Packaged in a 100-percent lead (Pb)-free shielded, composite construction that reduces buzz noise to ultra-low levels, the inductors offer high resistance to thermal shock, moisture, and mechanical shock, and handle high transient current spikes without saturation. The IHLE-2020CD-51 and IHLE-2020CD-5A are RoHS-compliant, halogen-free, and Vishay Green.
